. To all whom it may concern:

Be it known that I, DANIEL L. HoLunN a 'citizen of the United States,residing at t e borough of Manhattan, in the city, county, and ,State ofNew York, have invented a new and useful Improvement in Ice-Machines, ofwhich the following is a specification.

My invention relates to a means and method for making artificial icequickly and chea and .in a machine that is smaller, and by a method morequickly carried out than by the machinery and the method emloyed formaking artificial ice in cakes of arge size and appreciable wei ht.

The object of my invention sing to produce ice quickly, continuously andin a mass that can, as roduced or formed, be cut up into blocks 0 thedesired sizes-within prescribed limits-for immediate consumptlon.

In the machine of my invention I employ a hollow. cylindrical vessel,preferablv ver-' tically disposed and contalmng a refrigerant. The iceis formed on one or both surfaces of this vessel-the inner and outer--asthe result of spraying water thereon, preferably by a revolving sprayer.The ice, as formed, is loosened b scoring or crushing, or both, isremoved y a suitable scraper, and descends by gravity into a conicalhopper in which are revo ving scraper plates that work the fine icedownward in the hopper. This hopper is formed with a sur rounding waterjacket to drain off the water from the ice, the water being deliveredinto a tank. The ice falls into an ice compressor and former, preferablycontracted at the delivery end. A piston in this ice compressor-actuatedby suitable 'devices keeps constantly and progressively forcing the iceparticles to the delivery end of the compressor and former,simultaneously packing the ice into a solid mass of progressing length,in which the ice freezes solid and any free water flows away-by suitablemeans-into the same tank from which the water is preferably pumped up tobe sprayed in the continuous 1ce forming process, all of which ishereinafter more particularly set forth.

In the drawings, Figure 1 represents a vertical central section andelevation of substantially the complete device of my invention. Fig. 2is a section on a horizontal line at the upper part of Fig. 1, and inthe same proportion. Fig. 3 is a vertical section 0 operative deviceswhich are placed on top of the machine, as shown in Fig. 1, and havebeen drawn separate because the sheet holding Fig. 1 lacked the room.Fig. 4 is a side elevation of the ice com ressor and former on a smallerscale from ig. 1. Fig. 5 1s a cross section of the ice compressor anformer, and on the same scale at about the dotted line a: w of Fig. 1. 1Fig.6 is an inverted plan of the lower edge of the throat, connectingthe ice making device of the lee compressor and former. Fig. 7 is across section, in larger size, of one form of cfi'hndrlcal ice breaker.Fig. 8 is a plan, at t e upper end, of the cylinder containing therefrigerant, showin the u per end of one of'the scraping devlces, an thedevices for supportin and adjusting the same. Fig. 9 1s a verticalsection through the parts shown in Fig. 8, and Fig. 10 is an elevationand partial section at the lower end of the cylinder containing therefrigerant and lower end of one of the cylindrical breakers.

Similar letters of reference and numerals, throughout the drawings,indicate similar parts.

The foundation and sup ort of the ice making devices comprises a xedring a and a second fixed ring a, in a higher plane, the ring a beingsupported by columns b upon any suitable foundation, and the rings a anda connected together, and the ring a supported by columns b Thesecolumns are generally shown in Fig. 2 and may occupy a'staggeredrelation to one another.

0 represents a cylindrical casing secured to both, rings a and a), andadjacent to the inner edges of said rm The ring -a is provided, as awheel, wit spokes and a central hub a. The cylindrical vessel,vertically disposed and containin a refrigerant, comprises the spacedcylindrical walls d al These walls are held together by connectingrivets 2, and are held apart by the annuli 3, 4; certain of theconnecting rivets 2 also passing through said annuli. These cylindricalwalls 11 d are flanged at their upper ends, and the upper ring a isprovided wlth arms as spokes with a central neck piece a and ring a, andit is to this ring a that the walls of the cylindrical vessel,containing the refrigerant, are secured by suitable bolts or rivets,said vessel being thus suspended .from the parts of the upper ring. Iprovide suitable plpes for conveying the refrigerant into thiscylindrical vessel and for the exit also of the said material so as toestablish a circulation. Therefrigerant is preferably the usualanhydrous-ammonia. At the center of the aforesaid rings and the "clindri- The lower part is also contracted at 6 and asses through the huba. The lower ring orms a support and. guide and the upper ring'a guidefor the hollow, cylindrical axis e and the parts connected therewith.

Extending out from the member e are water pipes 5 and 6, as arms. Thepipe 5 terminates in .a spray nozzle 7 within the cylindrical vesselholding the refrigerant, while the pipe 6 extends out from the lowerpart of the member 6 and passes to the outside of the cylindrical vesselcontaining the refrigerant, and the pipe itself rises an terminates in aspray nozzle at 7, From both of said nozzles water is discharged againstthe inner and outer surfaces of this cylindrical vessel containing therefrigerant, and while Ihave thusshown the construction, I do not limitmy invention in this respect.

Referring particularly to Fig.3, a stand ard 8 carries a bearing at itsupper end for the shaft 9, which is rotated by any suitable power. Onthis shaft 9 is a bevel wheel 10 which meshes with a large bevel wheel11, the hub of which surrounds and is keyed to the tubular end 6 of thehollow cylindrical axis. At the upper end of this tubular part e thereis a water supply pipe 12, passing through a packing 13, and by thispipe water is introduced into the member or cylinder e from any sourceof supply, and therefrom through either or both the pipes 5 and 6 to oneor more (spraying nozzles 7. In connection with the hollow cylindricalaxis e I employ the rings f g.. The ring 7 is provided with arms 7secured to or formed in one with the hub e and secured thereto andbetween the lower ring 7 and-upper ring g,

there are a series of columns or supports 14, and I may prefer toconnect the upper end of the pipe 6 at its nozzle 7,t o'..,the ringngnfor additional support. v p

h and It represent equivalent forms of cylindrical ice breakers. Theform h is horizontally scored or grooved,and fthe form k is verticallyscoredfor. grooved,-

either form serving for the performance of an equivalent function incracking and more or less breaking off the ice forming upon the inner orouter surfaces of the cylindrical vessel containing the refrigerant. Asa means-providing for the support of the ice breakers h I have shownlugs 15, madepending from the arm f and the other connected to an arm 9extending-out from the member e. The respective ends of the breaker hare reduced, and eye-bolts receive these reduced ends, and, in turn,pass through the lug 15 and are held in position tion, whereby theperiphery of the breakers h maybe adjusted with reference to the innersurface of the cylindrical vessel containing therefrigerant. For the icebreakers h I have shown lugs 18, one extending, below the ring 7, andthe other risin 'from the ring 9. The respective ends '0 these breakersare also reduced and are received in eye-bolts 19, passing through thelugs '18 ing from the hollow cylindrical axis e. The

devices as scrapers for removing the ice from the 1nner surface of thecylmdrical vessel contalning the refngerant, are conby clamping nuts 17in an adjustable relanected to a support from the ends of these arms andconsist of scraper bars 6 coming to a sharpened edge at their advancingortions and, deflector plates 5 the'edges o the bars 6 scraping ofi theice and the plates i directin the ice away from the center of the macinc and below the inner surface from which it is removed. Where scrapingdevices are also em loyed against the outer surface of the cyllndricalvessel containing. the refrigerant, these scraping devices must becarried at their res ctive ends between the rings f and g, and or thispur ose I have shown specially, in Fig. 8, an illustration of a devicesuitable for such purposeqand comprising brackets of substantiallyUlshape 2' with an integral center screw stem 23, which passes through alug 22 on the ring 9, and is held inposition by clamping nuts atopposite sides of said lug.

The ends ofthe bracket 2' are slotted and receive screw pins upon whichare clamping nuts 24:; therefore, to adjust the position of theseoutside scrapers, various clamping nuts may be loosened and the devicesgiven a slightly radial movement to bring the scrapmg edge nearer to orfarther from the- =outer surface of the member d Fig. 9 shows a crosssectionv of this con-.

struction, which is also preferably employed at the lower end of theouter scrapers with reference to the ring f. Below the ice maklngdevices, just described, I place a conical hopper k, the upper'flangeedge ofwhich is secured to the under-surface of the fixed I ring a, atthe inner edge of the ring,and

preferablyin line with the inner surface of the casing a. This hopper isperforated and provided with a conical jacket 70 and a gauze lining m.Into this conical hopper all the ice made in and by the devices in thehigher plane,jand just herein described, falls progressively, togetherwith any water into we.

as surplusage that may not have been turned he water passes through theperforations of the conical hopper and the gauze lining, into the jacketis, and is conveyed away by a vertical pipe 25 into a tank I, the icepassing on down through the I hopper and being constantly agitated byscrapers 28. These scrapers 28 are preferably strips of rubber, with toother lower edges secured to a suitable metal frame, the

ends of-which in turn are secured to horizon-- tal-arms 26 and dependingarms 27 The arms 26 are in one wit a hub secured around and at the lowerend of the hub a, while the arms 27 are secured to the lower end of thehub e. Said arms and said scrapers rotate together with the hollowcylindrical axis e and parts connected therewith. I also provide a rod29 secured to the lower end of the hub e, and this rod carries a forkedagitator 30,

also rotating with the aforesaid parts at the lower end of the conicalhopper and its lace of union with the throat 31. This t roat 31increases in area from the lower end ofthe hopper to its union with theice compressor and former. This ice .compressor and former is supportedon standards 32. It generally comprises a body rectangular in crosssections, as shown in Fig. 5, in

which the lower part 0 is of substantially U shape in cross section ando is the top or cover, said parts being held together with bolts 33, atsuitable intervals.

The body of the ice compressor and former is scored longitudinally so asto produce the longitudinal internal ribs 34. There is, as shown inFigs. 1 and 4 a parallel sided section and a tapering section 0 to theice compressor and former, the said sections being secured together withthe bolts 35. The entire ice compressor and former is interiorlyprovided with a perforated lining r which backs up against the faces ofthe ribs 34, the lining extending from one end to the other of the icecompressor and former. As shown in Fig. 1, the left-hand end is providedwith a large nut s, and longitudinally the several arts are alsosecurely held to ther by tie ro s 36.

t represents a screw s aft passing through the nut s and 4; representsan electric motor secured upon theice compressor or former;

. o the shaft of the motor and '0 a gear; 37

screw shaft t and meshes with the gear or.

pinion '0 so that the power and rotation of the motor are communicatedthrough its shaft and gear to the large ear w. The screw shaft t islongitudinal y grooved and the fp a hub of thelarge gear w carries a'keyor spline secured thereto and moving in a groove of the screw shaft,whereby with'the rotation of the large gear the screw shaft t is alsorotated, see Fig. 4.

Within the ice compressor and former is a hollow piston u longitudinallymovable within the perforated lining r, and the right-hand end of thescrew shaft t is sccured in the left-hand end of the hollow pistonbetween the ball-beari heads 40 and 41, which are held to the piston bythe collar 39; consequent] as the screw shaft turns, it reciprocat'es trou h the nut 41, and moves the piston forwar and backward in the icecompressor. This piston is made.

with a head u connected to the tubular body of the piston by longscrews, and this head is perforated so that any water in the ice ascompressed may flow through the head and discharge into the scoring ofthe ice compressor through other holes inside the piston, all the waterin the scoring eventually advancing by drain pipes 42 into the commontank I, where the water as it collects is pumped out into the pipe 12,todescend into the cylindrical hollow axis a, to be again sprayedagainst the surface of the cylindrical vessel containing therefrigerant, in the repeating process of forming ice and removing thesame.

In the operation of the ice compressor and former, the ice descendswithin the same through this throat 31. The stroke of the piston isbetween the position shown in Fig. 1 and the forward end at the taperingsection; consequently, as the ice collects, it is periodically pushedforward bodily and forced up against the ice in the tapering section.The water is squeezed out, the ice so lidifying and the water advancingthrough the perforated lining r into the scoring and making its way bythe drain pipes 42 into the common tank Z. As the ice is forcedprogressively through the tapering section, it comes into the parallelend of the section back of the weighted cover 0 the ice meantimefreezing together into a substantially solid mass. As the ice emergesfrom the exit or mouth of the ice compressor and former, this weightedcover is lifted and gradually thrown back and remains back during thecontinuous ice making process. As the solid rectangular mass of iceemerges from the ice compressor, it may be cut up into sizes, asdesired, for immediate consumption, and by any suitable cutting means.

have shown in Fig. 10, a scraper 43 as secured to the arm f and comingunder the lower edge of the cylindrical vessel containing therefrigerant, for the purpose of scraping off the ice which ma form onthe lower edge of said vessel. I ave also shown on the free end of thescrew shaft t an upright member or block 44, adapted for employ- 1.
